Application filed `Tune 13,

My present invention provides an improved refrigerator, and, generally stated, the invention consists of the novel devices, combinations of devices and arrangement of parts hereinafter described and defined in the claims. ln the accompanying drawings, which illustrate my invention, several forms or embodiments of tie invention are illustrated.

Referring tothe drawings, wherein like characters indicate like parts throughout the several views:

Fig. 1 is a transverse vertical section taken through a refrigerator of the soscalled side icing type;

Fig. 2 is a front-to-rear vertical section taken through the refrigerator on the line 2-2 of Fig. 1;

Fig. 8 is a horizontal section taken through the refrigerator on the line 3 8 of Fig. 2;

Fig. l is a fr0ntto-rear section with some parts broken away, showing a refrigerator of the so-called top-icing type, involving my invention; and

5 is a horizontal section taken on the line 5 5 of llig. l.

Describing rst the construction illustrated in Figs. 1, 2 and 3, the numeral 6 indicates the refrigerator casing provided at one side of its upper portion with an ice chamber 7, below said ice chamber with a food compartment 8, and at the opposite .side of the refrigerator with a food compartment 9 that extends from bottom to top ofthe casing, and, in practice, will be provided with perforated shelves 10 indicated by dotted lines only in Fig. 1. r)The vertical partition 11 that. divides the interior of the casing into the compartments or chambers 7, 8 and 9 terminates above the bottom of the casing to all-ord a large air passage 12 and terminates below the top of the casing to afford a free air-return passage 18. The upper portion of the partition 11 forms the inside wall of the ice compartment, and this wall, as well as the top and side walls of the ic compartment, are lined with heavy layers of insulating material 14e. This insulatin g material 14 is in addition to the ordinary insulating material applied throughout the top, bottom and side walls of the main casing, and preferably this additional insulating material 14 is exposed, that is, is not covered with either metal or wood, but may be waterproofed, painted or enameled. The vertical side walls of the ice compart- 1.927. Serial No.. 198,340.

ment should be provided with metallic guard strips or cleats 15 that prevent the ice y from coming into direct Contact with the exposed insulation. The ice is placed on a suitable rack 16, which, in turn, rests on a metallic pan or bottom plate 1i" that forms the top layer of the bottom 18 of the ice compartment.

@pening through the bottom 18 of the ice compartment is a large cold air passage 19, which, as shown, extends a little less than from front to rear of the ice compartment, but might be extended completely from front to rear thereof. passage'l) is through an elongated metal sleeve 20 that is set through the bottom of the ice compartment and extends slightly above the pan 18 so as to prevent the ice water from running through the said cold air passage. Of course, the melted ice may be carried olf by the customary drain pipe, not shown. Secured to the bottom 18 of the ice compartment and extended below the cold air passage 19 and toward the left-hand side wall of thecasing, that is, away from the main food compartment 9, is a curved deflector 21. Applied to the top of the -ice compartment in a position to overly the cake of ice is a curved deector 22 that is preferably hinged at 28, so hat it may be raised when a large piece of ice is being placed in the ice compartment. rlfhe ice compartment 7 is shown as provided with the customary front opening door 24, the food compartment 8 is shown as provided with the customary door 25, and the main food compartment 9 is provided with the customary front opening door 26.

To facilitate the circulation of air, the casing is shown as provided at its two lower corners withcurvcd llets 27 and 28, and at its upper right-hand corner with a larger fillet 29. v

With the refrigerator constructed as doscribed, the cold air will be precipitated from the ice chamber through the cold air passage 19 and, by the deflector 21, will be directed toward the left-hand side of the chamber 8 and from thence will be caused to flow downward along the left-hand side of said chamber to the bottom thereof, and from thence through the lower air passage 12, thence upward through the main food compartment 9, and thence through the return air passage 18 to the top of the ice chamber 7. The air coming through the Preferably, this cold air return `passage `13 finto the top `of the -icc chamber will 'flow over the Ficefcake and its travel forward the left-hand side of `said ice chamber will be intercepted by the deector 22, with Vthe result that 'the air will Vbe caused to strike first and chielypupon the top of the ice cake and from thence downward around the fsides thereof. Even when the ice cake is small or is low, the de- 'fleetor T22 Iturns the return air `do\'vnw'arcl onto the iceandeprevents the same "from flo-w- Y Figs. 4 and 5,'ftheicecompartment 7a ofthe casinga is :located immediately above the main and -o'nly ffood provision chamber `9a.

`Said compartments 7a fand 9u-are providedv Xwith the customary doors, not shown. The cold KTair passage 19a, fas Vin wthe previously described structure, is extended through the central portion of *the @bottom 1'8a of -the vice chamber, 'and `the curved deiiector 2la is secured to/said *bottom below said cold air fpassage. The air `return passage '13%. inthis arrangement, is extended Athrough 'the fbot- `tom 18@L close tothe right-hand side of the casing, that is,fthrough^1th'at sideoffthe'casling' that "is away iirol'n'fthe side toward which -the downwardlymovingcold'air willlbe delected bythe defle'ctor21.

47WhatV I 'claim is:

'1. A refrigerator having ice and 'foodw compartments connected by vair-'circulating fpassages, a `'cold air Adischarge .passage located 'in'the'botto'mof said ice compartment,

and a downwardly concave curved deflcctor applied to'the'bottomof said ice compartment and extended under said cold air disthe ,inside of the 'food compartment for 2defleeting the air toward one side of the.

underlying food compartment.

2. A refrigerator having ice fand 'food' compartments connected by aircirculating passages, one 'of` which is 'in the 'bottom oi' said `-ice compartment, "a deflector vapplied at the top of said ice compartmentfor deflecting downward A"thefair "returned into the upper portion of said fice compartment, and `which deflector is Yhingedso that it ymay be moved upward 'to 'clear large pieces of ice.

3. A refrigerator Vhaving V'ice rand food compartments with air-circulating passages connectingthe same, oneof said air passages being a cold air discharge lpassage located inthe bottom of said ice compartment, a delector secured tothe bottom of said fice compartment- 'and 'extended lunder said cold fair 'discharge passage for deiiecting 'the downwardly moving coldair toward Vone side ofthe underlying food compartment,a delefctor at the vtopof said icecompartA ient arranged to 'downwardly deiiect 'the returning-air, whichnioves towardthat sideof theV refrigerator towards 'which the air is dc- Aflee-ted by said flower 'deflector, and which fupper deiiector is hingedso that it is -free -tofmovefvertically tofclear large piecesfofice.
